Assignment 0: C++ warm-up. The purpose of this assignment is to familiarize ourselves with C++, cmake, and github.
Windows
Open git bash to the directory containing this repository.
cpp-warmup $ mkdir build
cpp-warmup $ cd build
cpp-warmup $ cmake -G "Visual Studio 16 2019" ..
cpp-warmup $ make
Then open the solution file to write and test your programs.
macOS
Open terminal to the directory containing this repository.
cpp-warmup $ mkdir build
cpp-warmup $ cd build
cpp-warmup $ cmake ..
cpp-warmup $ make
To run each program from build, you would type
cpp-warmup $ ../bin/fizzbuzz
cpp-warmup $ ../bin/testcircle
In the file fizzbuzz.cpp, implement the program FizzBuzz, described here.
In case you might not be familiar with reading and writing data from the console, we've given you the following starter code.
#include <iostream>
using namespace std;
int main(int argc, char** argv)
{
int X,Y,N;
cin >> X;
cin >> Y;
cin >> N;
// your code here
}
This program will sit and wait until you enter 3 values.
Write a class, circle, that stores a radius and has the following methods
- default constructor (radius is set to 0)
- constructor taking a radius as argument
- copy constructor
- assignment operator
- output stream operator
- add operator (should add the radii of two circles together)
- accessor (e.g. getter) for radius
- mutator (e.g. setter) for radius
- method for computing and returning the area
Your class should also
- Split the class into a header and implementation file
- Define its methods as public, but data (the radius) as private
For example, running the program, testcircle.cpp, should give the following output.
#include <iostream>
#include "circle.h"
int main(int argc, char** argv)
{
Circle c1;
Circle c2(10);
Circle c3 = c2;
Circle c4 = c2 + c2;
std::cout << "--------- Starting Values ----------\n";
std::cout << "c1: " << c1 << std::endl;
std::cout << "c2: " << c2 << std::endl;
std::cout << "c3: " << c3 << std::endl;
std::cout << "c4: " << c4 << std::endl;
float area = c3.computeArea();
std::cout << "Circle 3 has area: " << area << std::endl;
c2 = c1;
c1.setRadius(c3.getRadius() + 2);
std::cout << "--------- Ending Values ----------\n";
std::cout << "c1: " << c1 << std::endl;
std::cout << "c2: " << c2 << std::endl;
std::cout << "c3: " << c3 << std::endl;
std::cout << "c4: " << c4 << std::endl;
}
Output
--------- Starting Values ----------
c1: 0
c2: 10
c3: 10
c4: 20
Circle 3 has area: 314.159
--------- Ending Values ----------
c1: 12
c2: 0
c3: 10
c4: 20
